Title: Hemostatic agent delivery device having built-in pressure sensor
Inventor: VAN TASSEL ROBERT A
IPC: A61M25/06
Filed: 1998-02-27
Abstract: An instrument for achieving rapid hemostasis at the conclusion of a catheterization procedure comprising a hemostatic agent injection device for use with a conventional introducer sheath used to gain access to the blood vessel. The injection device includes an elongated tubular member having ejection ports proximate its distal end. A hub member is located on the proximal end of the tubular member and includes an elongated groove or track located in its surface with a transparent cover. The enclosed track is in fluid communication with the lumen extending through the tubular member. After the catheterization procedure, the instrument is inserted into the introducer sheath. Blood flows into the lumen of the device and into the enclosed track. The leading edge of the blood pulsates within the enclosed track, clearly indicating that the ports are located in the blood vessel and subjected to variations in blood pressure. The instrument and introducer sheath are then slowly retracted as a unit in the puncture wound. The blood flow will stop pulsating in the enclosed track when the ports have exited the blood vessel wall. A hemostatic agent is then injected by the instrument adjacent the vessel wall.

Title: Enzyme treatment to enhance wettability and absorbency of textiles
Inventor: COLLIER KATHERINE D
IPC: C12S11/00
Filed: 1997-03-06
Abstract: Textile fibers are treated with enzymes in the absence of surfactants, with the effect of increasing the wettability and absorbency of the fibers. The enzymes are pectinases, cellulases, proteases, lipases or combinations thereof. The wetting properties of cotton fibers are found to be most substantially improved by treatment with a mixture of cellulase and pectinase.  The effects of five hydrolyzing enzymes on improving the hydrophilicity of several polyester fabrics have been studied. Four out of the five lipases studied improve the water wetting and absorbent properties of the regular polyester fabrics more than alkaline hydrolysis under optimal conditions (3N  NaOH at 55 ~C for 2 hours). Compared to aqueous hydrolysis, the enzyme reactions have shown to be effective under more moderate conditions, including a relatively low concentration (0.01 g/L), a shorter reaction time (10 minutes), at an ambient temperature (25 ~C). Contrary to the results with alkaline hydrolysis, the improved water wettability is accompanied by full strength retention. Lipase has also shown to be effective in improving the wetting and absorbent properties of sulfonated polyester and microdenier polyester fabrics.

Title: Premixing fuel injector and method of operation
Inventor: SOWA WILLIAM A
IPC: F02C3/30
Filed: 1999-05-17
Abstract: A premixing fuel injector for an industrial gas turbine engine includes an axially extending centerbody (58) and a pair of radially offset scrolls (18) bounding a mixing chamber (24). The leading end (28) of each scroll cooperates with the trailing end (34) of the neighboring scroll to define an intake slot (42) for admitting a stream of primary combustion air (44) tangentially into the mixing chamber. Fuel injection passages extend along each intake slot for injecting jets (76a, 76b) of primary fuel into the incoming airstream (44). The injector is operable in a prescribed or normal state, and in a degraded state associated with the presence of undesirable combustion inside the mixing chamber. The fuel injection passages are oriented and positioned so that the fuel jets issuing therefrom are ineffective at sustaining the undesirable combustion for more than a limited interval of time. In one embodiment of the invention, the injection passages are positioned so that the trailing end (34) of the neighboring scroll acts as a physical barrier to limit radial penetration of the fuel jets when the injector operates in the degraded state.
